BESTOBER or Roman IGNITION FOR non. IGNITION ArrAnA'rUs or INTERNAL-comnus'rron mamas.

Application filed July 31,

To all whom it may concern: I

-Be it known that I, JULns COURTIER, a citizen of the Republic ofFrance, of 20 Rue Ernest Cresson, Paris, France, have inventedImprovements in or Relating to Restorers of Normal Ignition for DualIgnition Ap aratus of Internal-Combustion Engines, 0 which the followingis'a full, clear, and exact description.

This invention relates to an auxiliary aparatusfor internal combustionengines havlng dual ignition for producing regulable break s arks fordoing away with misfires due to the sooting of s arking plu s andautomatically cleaning t ese ln s during the running of the engines an othe vehicles driven by them.

This apparatuspermits a singlecontrolling organ-to efl'ect theintroduction of break sparks regulable at will, separately into one orthe other of two ignition circuits.

The general arrangement I is such that when the apparatus is at rest thetwo ignitions work without any secondary spark gap, and when one of theigpitions is working with break sparks the ot er ignition continues towork without break sparks.

The invention is represented in the drawing', by way of example only,wherein there is shown an arrangement of the apparatus comprising twopairs of contacts capable of being separated to any desired extent, eachpair corresponding with one ignition.

As shown in the drawing each of the pairs of contact rods A and A(corresponding to the ignition circuits M and M is composed of a fixedcontact and of a movable contact.

' The fixed contacts 1 and 1', are mounted in a block of insulatingmaterial 2, and they pro'ect from the block into the interior ofcavities 3, 3', and are respectively connected to one of the poles ofthe electric current by plate springs 4, 4', fixed to the terminals 5,

5' which are mounted in an insulating ca'sing 6. These fixed contacts 1and 1 are pro-.

vided with projecting flanges 7, 7

The movable contacts 8, 8', also provided with projecting flanges 7, 7',arethemselves mounted so as .to project to the interiorof the cavities3, 3", below the fixed contacts 1, 1', and to slide in sockets 9, 9',mounted in the insulating block 2.

They each comprise a tubular part 10, 10.

These tubular parts, provided with lateral openings 11, 11', arerespectively closedat 1823. Serial No. 654,879}.

their lower part by screw plugs 12, 12. In the interior of the tubes 10,10 are placed coiled springs 13, 13', resting upon the pistons 14, 14.The movable contacts #9, 8 are connected to the second pole of thecurrent by plate springs 15, 15', fixed to the terminals 17, 17, mountedin the casing 6. The screw plugs 12, 12 rest freely upon the ends 16, 16of these sprin s. r A rocking iece 18, made of insulating materialturning upon a pivot 19, is provided with arms 20, 20, whose ends areconstituted by heads 21, 21', projecting respectively into the interiorof the tubes 10, 10', through openings 11, 11', between the screw plugs12, 12, and the pistons 14 and 14.

The rocking piece 18 is formed at its upper part with a slot 22 in whichis freely located the finger 23-of a disc 24 turnin upon its centre 25under the action of the handle Notches 27 are provided upon the casing6. The object of t ese notches will be hereinafter explained.

The working of this apparatus is as follows:

When the handle 26 is moved in the direction of the arrow 0:, the finger23 causes the rocking piece 18 to pivot, towards the'left.

produced a break spark Whose length in creases as the handle 26continues its move ment in the direction of the arrow at.

i no

The handle 26 is provided upon its lower face with a stud 28, whichenables it to be secured in' one of the-notches 27 of the easing 6. Inthis manner it is possible to regulate the gap between the fixed contact1 and movable contact 8, and consequently 'the length of the sparkbetween these contacts. At'the same time as the arm 20 is being lowered,the arm 20 is moved upwards;

the head 21 presses upon the piston 14 and compresses the coiled spring13. An

upward pressure is therebyproduced upon the inner end 29 of the tube10', so the 0011- v is.

tact between the movable contact 8' and the fixed contact 1' is so muchthe better ensured.

It-will be understood that in operating the handle 26 in the directionof the arrow 6, the movable contact 8 will be removed from the fixedcontact 1, while ensuring on the other hand the thorough pressure of themovable contact 8 against the fixed contact 1.

When in the normal position of rest, the arms 20 and 20 of the rockingpiece 18 remain horizontal as shown in the figure, and the plate springs15 and 15, through their ends 16, and 16', ensure contacts between thecontacts 1 and 8 on the one hand and the contacts'1 and 8' on the otherhand.

The two circuits M and M then workwithout any secondary spark gap.

The cavities 3, 3 are enclosed by sheets of mica or any other suitableinsulating material.

The apparatus above described is used in the followingmanner:

In engines with fixed cylinders, the apparatus described is inserted sothat it is arranged, as far as concerns the electrical connections,between the collector and the distributor of the magneto'of the firstignition circuit through its terminals 5 and 17, and between thecollectorand the distributor of the magneto of the second ignitioncircuit through its terminals 5 and 17 As concerns the electricalconnections to rotary engines the apparatus is inserted between the coector of the magneto and the distributor of the cylinders of the firstand of the second ignition circuits respectively through the sameterminals, 5,17 and 5', 17'.

In case of misfires, the handle 26 is moved in the direction of one ofthe arrows a or b proceeding gradually notch by notch. If, in the firstdirection chosen the misfires are heard to cease, the handle issecuredat the point where it was noticed that good ignition was reestablished.If the handle is moved in one direction until the last notch is reachedwithoutd nition being restablished, it is 'conclud that the misfire isproduced in the other ignition circuit. The handle is then brought backto its medium position of zero and it is advanced gradual ly notch bynotch in the opposite direction. After a few trials the motor is -heardto be working normally without any misfire. The handle is secured at theignition was re-established. At the end of a few minutes, necessary forthe cleaning of the sparking plug, the handle is returned to zero.
